Can we get a sub-forum for the Access Virus (all models)?

Anyway, I learned something very interesting about my Virus B - the LFO contour function. This morphs the LFO from one waveform to another. A sine is morphed to either a triangle or a square. A triangle morphs to a sawtooth. Sawtooth morphs to either a square or an exponentially declining decay. A square has its PW modulated. For all other table waveforms, contour zooms in on the wave and shortens it.

If you crank up all the values on an LFO while using max contour, you can get some really wild stuff.
